The Eye of the Sahara, seen here in an aerial image provided by the ISS, is is a prominent circular feature in the Sahara desert near Ouadane, west–central Mauritania. It was initially thought to have been caused by a meteor impact, but lack of strong evidence has turned many off to this hypothesis. At 30 miles wide (50 km) it is easily visible from space.
